This is the minimap from loading up your Replay just now:
Notice that the top of the crescent island is slightly cut off by the map border. The map is larger than the battle area, but the boundaries are set to define the battlespace for the Operation.
Your picture shows a different map size relative to the actual operation boundary:
Notice how the Crescent Island is fully within the boundary and there is more space above it than should be normally allowed.
My guess is that you have some form of mod which affects the minimap. The mod may work correctly on all the other maps as the boundaries are set correctly, but it would seem that this map is not correctly set for the mod and you are seeing wrong information because of it.
As with most issues, when you are experiencing something abnormal please consider disabling all your mods first to see if the problem continues.
Threads can be closed by request of the OP if they have received the answer to their question or feel their discussion has run its course.
It's not appropriate to call for the closure of someone else's thread simply because of a disagreement. The thread will remain open until the OP finds their answer and requests it is closed or moderation is required because the discussion has turned bad. Otherwise the thread stays open and goes dormant over time as conversations move elsewhere.
